Stainless Steel Color Change Temperature. The colors are affected to some extent by the composition of the steel and the method may not be dependable. Melting points of heat treating baths.
The molybdenum alloy steels to approximately 850 f 454 c. And the stainless steels to considerably higher temperatures depending upon the type used. The color of steel is a great way to work out how hot the metal has been.
Temperature of 750 f 399 c.
The mp of these steels depends on the composition and quantity of the alloying metal. Temperature of steel vs. If steel is heated up slowly this color will be noticeable. As the thickness of the layer increases the wavelength of light transmitted changes and hence the color we see.
